baby boa feeding

hey guys i was just wondering if a baby boa super small wont eat if the prey item is to big and if its stressed i had him in a 20gal tank but just moved him into a 12 quart tub ive had him for 2 weeks and ive treid feeding him 2 F/t rat pups and 1 live mouse next time im going to try feeding a rat pinkie surprisling without eating hes gained 2 grams?

What do you have for temperature and humidity? Do you have a hide for it? I brought my boa home from the expo and the same night it ate a large f/t mouse.

From my experience with my baby boa... Do you mist his enclosure every night, temps warm enough, and enough hides? My Boa fasted for a couple of months and then I realized he needed more humidity so I started misting lightly every night, 2 days later he ate a nice fat rat pup for me.

How old is this boa? Any pics of him/her? I've had boas shipped to me that ate same day without any problems. What are you temps like?
